Application filed September 6,1916, Serial No. 118,664.

To all whom it may concern:

Be it known that I, ARNOLD W. PUPKE, a citizen of the United States, anda resident of theborough of Manhattan, city, county, and State of NewYork, have invented a certain new and useful Machine for the ContinuousManufacture of Cement length, the smaller the pipe ordinarily thesection, and each shorter the length of each a so-called bell sectionhas ordinarily had or socket on one end in which the nonupon socketedend of the adjoining section entered, thus serving as a means to centerand sustain consecutive sections in proper alinement, cement beingusually deposited about the joint. These old forms were expensive tomanufacture, their weight was increased and consequently the labor andexpense of laying them, particularly because of the cement required, wasalso increased.

It is the purpose of my invention to so construct a machine that thetile or piping will be produced as a continuous unbroken structure ofindefinite length and deposited in the bottom of the trench orexcavation where it is to remain.-

Referring to the drawings, Figure 1 is a plan view of the machine; Fig.2 is a sidewise elevation of the machine, partly in section, taken onthe line 2-2 of Fig. 3, looking in the direction of the arrows; Fig. 3is a front elevation of the machine; Fig. 4. is a transverse verticalsectional viewon the line 14 of Fig. 2, looking in the direction of thearrows; Fig. 5 is a longitudinal and diagonal sectional view on the line5-5 of Fig. 3, looln'ng in the direction of the arrows.

, In order that the construction and method of operation of the machinemay be more readily understood, it should be stated that the bottom ofthe trench or other surface which the pipe is to be laid, should beprepared and graded prior to the use of the machine. A suitablyconstructed track, which may beneficially be made of ordinary two byfour studding nailed together on the break joint principle, should thenbe laid in the bottom of the trench or upon the surface which is toreceive the pipe, and along this track the machine about to be describedwill move during the making and laying of the pipe.

Referring to the. drawings, 1 is a rectangular frame upon which theapparatus is supported. It may be made of any preferred material,preferably angle iron as shown, and in any preferred manner.

2, 2, are a series of rollers, preferably in the form of flanged wheels,as shown, upon which the apparatus is supported and moved upon thetracks 3, 3, (see best Fig. 3) which, as stated above, are laid in thebottom of the trench or upon the surface on which the pipe is tobelai'd. v

4-is what may be called a plowshare ex cavator. It is made rounding onits forward edge as shown best in Fig.3, and "has a downwardly extendingpoint or forwar end 5-, as best seen in Figs. 1 and 2. As the plowshareextends rearwardly it expands to the right and wardly after I plow,forming mold boar to spread to the rightandleft cavatedby the forwardpart of the plowshare.

At the rear of themachine and suitably supported upon the frame are whatmay be ds 6, ,6, adapted called reverse mold boards7, 7, which aresolocated, shaped and set at such an angle as to draw inwardly again anddeposit against the rear part of the cement chamber, hereinafter to bedescribed, this maleft and rolls over outthe fashlon of a railway snowthe earth exterial, so that as the machine advances it will be depositedabout-and upon the newly made pipe. v

8 is a shaft supported upon bearings 9, 9, upon which is a grooved wheel10. a

11 is a bevel gear fastened to the side of the grooved wheel 10 whichdrives the beveled pinion 12 mounted upon a countershaft 13 supported inbearings 14:, 14:, best seen in Figs. 1 and 2, upon which is a pinion15, which meshes into another pinion 16, which is mounted upon a hollowshaft 17 (see Fig. '5) which runs through the machine, passingthroughthe compartments 18 and 19. Upon the shaft and within thecompartments is a worm longitudinally feed 20. The forward end of the'compartwhich forms onewell of an anment 19 is partly Y in this annularchamber 22 -mental worm there be eventfailing to feed will also removefrom the radial slots, as shown,

nular chamber 22, its other wall being the outer wall 19' ofthecolnpartment 19, and is a supplefeed 23, which is connected with theshaft 17 in any Suitable manner and is driven by it.

Above the compartment 18 is a hopper 24 and above the compartment 19 isanother For convenience these hoppers as a single structure and divld'edby a partition 2?. In these hoppers respectively are what maybe calledrotary strippers 25 and 26. They are peculiarly shaped devices best seenin Fig. 5, and are in effect solid disks, each inwhich slots the wormsengage respectively, so that should any tendency on the part of thematerial either to adhere to the worms or to ,revolve with the wormshaft, in either longitudinally, then these strippers will not onlyprevent revolution of the material with the shaft, but worms any part ofthe material which adheres thereto, and

hopper 24. may be built thus the material will be compelled to feed"longitudinally under the made.

action of the worms. Each of these strippersis mounted upon a suitablesupporting axis or center 27 28 (see Figs. 2 and 5) is a wire, cord, or,if preferred, a rubber hose, which is fed from a reel placed inadvanceof the 'machine and passes through the hollow shaft 17 and isdeposited in or near the center of the core for the pipe as it is beinglaid.

The operationofthe machine is as follows: The trench made and the tracklaid therein or thereon as above described the machine .is placedpreferably at an end ofthe line of pipe tobe Core-making material,preferably sand, which has been screened, although suitable earthOrequiValent'm'ateriaI may be 'used, is deposited in the compartment 18through its hopper; 24, and sand, preferably screened, mixed with asuitable proportion of cement: and water, as is well known, isdeposited'in the compartment 19 through its hopper'24 It will be notedthat the material in the compartment 18 will entirely surround and coverthat portion of the worm 20 which is within the compartment and willalso solidly fill that part of the comwire, rope or hose 28,

partment19 which -is within theshield 22, and that the sand cement andwater will entirely fill the annular chamber 22. The as the case may be,

is unrolled fromits reel and is passed through the hollow shaft 17,asindicated best in Fig. 5, and itsend is made fast to some suitableanchorage. One end of a draft rope' or cable not shown, is attached to asuitable anchorage in advance of the machine and distant therefrom asfar as desired, the free end of which is passed around having a seriesof,

or excavation havin beenthe grooved wheel 10 and carried back again to asuitable source of power, which may be a Windlass, a mot0r,'a tread millor the like. The power being now started, the machine, under the actionof the along the track; the plowshare will out a semi-cylindrical grooveor bed for the pipe in the surface along which the pipe is to be laid;the front mold boards of the plowshare will remove the excavatedmaterial to the right and left, depositing it by the side oftheadvancing machine, and it can not fall back again into the excavationmade by the plowshare, because the lower exterior surface of the body ofthe machine, shown best at 19, in Fig. 4, which extends rearwardly tothe point where the pipe forming cement is projected from the machine,will rest always in the bed out by the plow and maintain its contour,and smooth and compact its surface. The traction of the line over thegrooved pulley lOj'will powerfully rotate it, and thus drive the chainof gearing described, rotating the hollow worm shaft 17 and the feedingworms 20 and 23 attached to it, so that the worm 20 will continuallydischarge from the rear of the machine a core of sand or-other materialand the worm 23 will continually discharge from the rear of the machinea hollow cylindrical body-of plastic cement, which will surround and besupported by the core ejected by the worm 20. As the plastic cement bodyis delivered at the rear of the machine, the mold boards 7 7, which, asstated, are located at the rear end of the machine, will draw thematerial excavated by the plowshare and moved laterally by the frontmold boards 6, inwardly against the upper half of the outer wall 19 ofthe chamber 22, so that as the machine advances, this material will bedeposited about and upon the upper half of'the newly made pipe. Thus thepipe will be sustained throughout its lower half by the bed made for itby the machine, on its upper half by the material deposited upon it asstated, and by the core interiorly, until it is sufliciently set orhardened to be self-sustaining, after which it"will of courseadditionally harden and, as is well known, become monolithic. As themachine advances, the rope, wire or hose 28, as the'case may, be, willbe unreeled and deposited in about the center of the core, thus formingcontinuous removable device extending is made, whereupon the materialmay be draft line, will move completely washed out in a step of the pipea matter of depending upon ing may readily washed out. If this device bea rubber hose, which I prefer, then upon the completion'of the pipeforming operation, it may be pulled forwardly afew feet at a time andwater under pressure forced through it, so that the core materiab willbe by step manner as the hose is step by step withdrawn.

1t w'll be noted that there must be a certain relation between the feedof the'core making material and the mixed sand, ce-

' ment and water by the worms and the forward speed or movement of themachine, so that there will never be any failure on the part of themachine to get out of the way formation, for if it does notadsubstantially the same spee as then the cement and core vance with thepipe is made, material being continually ejected wo pile up in rear ofthe machine in a shapeless mass or accumulation. Also I prefer to sotime the operation of the parts involved that-the cement shall beejected under suflicient pressure to compensate for the thickness of'theshells 19' and 22.

It will also be noted that be of such length as desired. pletion of onesection of taken up and transferred to the next section the track may inadvance of the machine and thus be used indefinitely.
